public class AreaLegendPart

extends LegendPart

Represents a legend that refers to areas in a chart and looks for example like this:

It uses small, filled rectangles to refer to the area with the same paint.

The size of the square and the pen of the square border can be specified in this class, the orientation and all other properties in the super class.
